How to state the compass direction between two coordinates

What code can state the direction between two coordinates?

For example,

Input a,b;c,d (a,b to c,d)

a,b (x,y coordinates from place 1) to b,c (x,y coordinates to place 2)

Output: N,NE,E,SE,S,SW,W,NW or here (if it's the same place)?

Number examples:

Input: 1,1;1,2

Output = N

Input: 1,1:2,1

Output = E

Input 1,1:2,2

Output = NE

Input: 1,1:0,0

Output = SW

Input 13,13;13,13

Output = 'Here'

You would do

angle=atan2d(d-b,c-a);

and then, based on the numeric value of angle, assign a compass direction:

Yes that function is perfect. How though would you donate the input variables to a,b;c,d format?

i.e how would you link input 1,2;3,4 to a,b;c,d for the formula?

Actually dont worry. I found this relating to the variables...

thanks for the help.
